liquid to the machine whereby to maintain the dryer at maximum dryingcapacity.

More specifically, the invention embodies the provision of a floatcontrolled valve for the liquid distributor pipe and includingcounterbalancing means for the valve to insure a proper opening andclosing thereof when very light and frothy bodied liquids are suppliedto the dryer.

A still further object is to provide a hollow float of light weightmetal of elongated construction and having a V-shaped bottom for workingclosely between a pair of dryingrollers or drums and to further providea combined float hanger and breather pipe for the float to prevent thefloat from collapsing due to vacuum created by high temperature of theliquid.

A still further object of the invention is to pro vide an apparatus ofthis character of simple and practical construction, which is eflicientand reliable in operation, relatively inexpensive to manufacture, easyto install in operative position on a conventional milk drying machinewithout necessitating any changes or alterations in the constructionthereof and which is otherwise well adapted for the purposes. for whichthe same is intended.

Other objects and advantages. reside in the A vated position above thecoacting peripheries of the rollers and longitudinally thereof by endplates 9. The distributor pipe 8 is provided with of the valvelongitudinally of the pipe 8.

details of construction and operation as more fully hereinafterdescribed and claimed, reference being had to the accompanying drawingsthe rocker arm for the control valve and with I the combined floathanger and breather pipe shown in section, and I Figure 4 is an enlargedfragmentary sectional view taken on a line 44 of Figure 1.

Referring now to the drawings in detail wherein for the purpose ofillustration, I have disclosed a preferred embodiment of the invention,the numeral 5 designates a conventional milk drying machine whichincludes a pair of coacting hollow drying rollers or drums 6 journalledat. each end on brackets 1. Milk or other dairy liquid is supplied tothe rollers by a perforated distributor pipe 8 which is supported in anelea control valve In and a cut-ofi valve ll, both of said valves beingof conventional construction of a globe type for opening and closingmovement by a rotary valve stem l2.

A rocker arm [3 is secured to the valve stem l2 for the control valve Inbymeans of a nut l4, the ends of the rocker arm extending oppositely Thefront end'of the rocker arm i3 is provided with a pin 1 5 on which thedownturned end l6'of A hanger rod 2| is attached at one end to the otherend of the float l9 and is inclined upwardly therefrom and formed withan eye 22 at its upper end for attaching to the distributor pipe 8 by abook 23. I

A weight 24 is slidably carried on the rear end of the rocker arm 13 andis secured in longitug ijnally adjusted position thereon by a set screwIn the operation of the device, the valve I0 is set in a desired openposition for supplyinga pre determined quantity of liquid between therollers 8 by the distributor pipe 8 and the weight 24 adjusted so thatthe level of the liquid will be main tained at a pro-per operatingefficiency between the drums as shown in Figure 2 of the drawings.Variations in the level of the liquid will raise or lower the float I 9to open or close the valve as the case may be. I

Thecounter-balancing weight 24 for the float will aid in the promptmovement of the float, particularly where light bodied or fluffy liquidis being dried by the machine, a The tubular hanger I! also functions asa. breather pipe for the hollow float and prevents collapsing thereofdue to vacuum created by high temperatures of the liquid. A

In view of the foregoing description taken in l i conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device wlll be quiteapparent to those skilled in this art.
